あら、困りましたね。奥にカゴがありますから、出して良いと思いますよ。
あら、こまりましたね。おくにかごがありますから、だしていいとおもいますよ。
Oh, that's troublesome, isn't it? There's a basket in the back, so I think it's okay to take it out.
Gesture & etiquette
Point to the washing machine, then make a 'take out' motion with hands.
Do not touch other people's clothes without permission if possible. Ask for advice or wait. However, in coin laundries, it's sometimes tolerated to move laundry to a basket if no one returns for a long time.
